GN 581 swivel lifting eye bolts
offer a high load carrying capacity and are tested to meet high
safety standards.
The nominal values for load capacity in the
table are for the most disadvantageous loading conditions, and are also clearly marked on the ring.
Unlike DIN 580 lifting eye bolts, the GN 581 lifting ring bolt
is captively mounted in the ring housing, yet rotates freely. The hexagon socket head bolt cannot be removed from the ring. The ring can be
positioned in the direction of the load to make use of its optimum
strength. The higher load bearing capacity as compared with
DIN 580 lifting eye bolts permits the use of smaller mounting
bolts.
Hex key cover plate allows assembly without the need to use tools: inserting the hex key in the hexagon socket of the bolt allows the bolt to be turned by hand.
GN 581 lifting eye bolts comply with Mechanical Engineering Directive 98 / 37 / CE and are BG tested.

Safety Instructions:
The values given in parentheses refer to the load
capacity of the corresponding DIN 580 lifting eye bolt. If such
a value is not indicated the use of lifting eye bolts DIN 580
is not permitted.
The bolt-on surface of the lifting eye bolt must be plane and at a right angle to the threaded borehole. The countersinking must be </= the nominal diameter of the thread.
The shoulder of the socket screw
must be in full contact with the surface and the eye bolt must
be able to rotate through 360°.
Before applying the load, turn the lifting eye bolt in the direction of the force. The lifting eye bolt is not suitable for frequent rotation cycles under load.
In the case of assymetrical load distribution, each eye bolt
must be capable of carrying the total load alone.
In the case of load method G1, no cross load forces are exerted
on the eye bolts.
The load values given apply for the following data: Material:
mild steel, tensile strength >= 37 kp/mm2 Mounting
thread length: l2 >= d x d1 Load capacity
for other materials and mounting length of thread on request.
Operating instructions with more details and specifications are included with order.
